Abstract

The present relates to a method and a system for identifying an application type from encrypted traffic transported over an IP network. The method and system extract at least a portion of IP flow parameters from the encrypted traffic using at least one of specific target encryption types. Then, the method and system transmit the extracted IP flow parameters to a learning-based classification engine. The learning-based classification engine has been trained with unencrypted traffic. Then, the method and system infer at least one corresponding application type for the extracted IP flow parameters.
